' SPECIFICATION forming part of Letters Patent No. 691,886, datedJanuary 28, 1902.

Application filed March 8, 1901- Serial No. 50,336. (No model.)

To all whom it may concern.-

Beitknown that I, FERDINAND A. R. ADAM, .a citizen of the United States,and a resident of Southport, in the county of Fairfield and.

State of Connecticut, have invented certain new and useful Improvementsin Street- Lamps, of which the following is a specification.

My invention relates to an improvement in which the lamp is desired toburn.

To enable others to understand my invention, reference is had to theaccompanying drawings, in which- Figure 1 represents a front elevationof the damp. Fig. 2 is a broken detail upper plan view of the lamp bodyor reservoir. Fig. 3 is a detail elevation of the wick-regulatorprovided with notches or gages on both edges :adapted to be alternatelyengaged by springfingers. Fig. 4c is a detail upper plan view of thespring-fingers, a sectional view of the regulator on line a a of Fig. 3showing one of the spring-fingers engaged with the regulator while theother spring-finger is forcibly held out of engagement, also a View ofthe T- shaped guard to prevent the engaging springifingers being liftedwhen the regulator is raised. Fig. 5 is a view similar to the one shownat Fig. 4, except that the position of the spring-fingers are reversed.it Fig. 6 is a broken sectional view of the upper surface of thereservoir, a sectional view of the springfingers on line e e of Fig. 2,a broken View of the regulator, and a front elevation of the T-shapedguard looking in the direction of arrow 6, Fig. 2. Fig. 7 is an upperplan view of the hood and awning of the lamp looking Fig.. 8.

in the direction of arrow 0 of Fig. 1. is a plan view of theunder sideof the awning and a sectional view of the side drafttubes on the line (1d of Fig. 1. Fig. 9 is a frontelevation of the font with parts brokenaway to illustrate the relation of the wickregulator thereto.

Its construction and operation are as follows:

1 represents the awning of the lamp, which heretofore has usuallyconsisted of a round flat disk slightly convex, so as to freely shedWater but the water so shed runs 06 at the edges, to the annoyance ofthe lamplighter. To obviate this difliculty, I have provided thevertically-extending flange 2, (see also Fig. 7,) extending entirelyaround the outer edge of the awning, with the exception of the opening 3at the rear. This arrangement will collect the water falling on theawning and cause it to be discharged at the rear and away from thelamplighter. This flange may either be a separate piece attached to theedge of the awning, or a beading may beformed on the outer edge bysimply turning up such edge.

During a driving rain-storm it is difficult to find a dry place on"which to ignite a match.

For this purpose I have located the scratcher 4 on the under surface ofthe awning 1, for the reasons, first, that this place is always freefrom moisture; second, it being situated close to the chimney-opening 5the match can as soon as ignited be carried into said opening, and thusbe protected from the wind until it burns freely enough to prevent itsbeing blown out when brought down for the purpose of'lighting the lamp.

l The wick-regulator consists of the vertical fiat metal rod 6,operating throughthe elongated slot 7, extending through the uppersurface 8 of the reservoir 9.

10 is a pan or plate attached to the lower end of the regulator and onwhich plate the wick (not shown) is adapted to rest. As this plate andits relation to the wick are well known, no further description isnecessary, except it might be stated that when the reservoir is filledwith oil the burning-time of the lamp is regulated by the depth of thisplate in the oil.

The present lamps in use have a gage composed of a series of notches fon one edge of the regulator to be engaged by a spring-finger. Thesenotches are situated a distance apart to represent four hours burning,two representing eight hours. Setting the gage at every other notchrepresents eight hours, which is the length of time usually required forwinter nights, and when set at every notch ;it will represent about thelength of time required on moonlight nights. Now six hours burning isabout the average length of time required in summer; but owing to thefact that it would be impracticable on account of the limited space toadd any more notches on this edge and the still further difficulty offinding the right notch on a dark night the eight-hour gage is used insummer as well as in winter. This results in a useless waste of oil. Myimprovement consists in forming the notches g on the opposite edge,which represent six hours burning for summer. These can be subdividedonce, so that it will be as easy to locate any particular notch on thisedge as on the other, which, as before mentioned, has just enough to bereadily found, but cannot accommodate any more.

11 and 12 are spring-fingers whose free ends are adapted to alternatelyengage the notches in the regulator and hold the same suspended.

l3 and 14 are stops projecting from the upper surface of the reservoirto be used for holding the spring-fingers out of engagement with theregulator. For instance, when the notches are used on one edge of theregulator and the spring-finger 12, Figs. 2, 4, and 6, is engagedtherewith the other spring-finger 11 is thrown around the stop 13 andout of engagement with said regulator. In using the opposite edge ofsaid regulator the spring-finger 12 is thrown around the stop 14 and thespringfinger 11 is brought into engagement with the notches in theregulator, as shown at Fig. 5. The T-shaped guard 15 prevents whicheverof the two spring fingers that is engaged with the regulator beinglifted and broken when the same is drawn out, while the upper surface 8of the reservoir will of course prevent them being forced down when theregulator is pushed in. It will be observed in Figs. 4 and 5 thatwhichever spring-finger is engaged with the regulator it forces it hardagainst the opposite end of the opening 7, and thus holds said regulatorfirm and rigid, so that no jar or vibrationwill displace it. For thispurpose (see also Fig. 6) the vertical wall of the guard 15 is cut backfar enough to be cleared by the spring-finger. It will therefore readilybe seen that the above-described improvements are of great advantage inlamps of this character, particularly the improvement relating to theadvantage derived from being able to set the regulator for any desirednumber of hours, and thus effect a great saving in consequence both asto time and oil.

Having thus described myinvention, what I claim as new, and desire tosecure by Letters Patent, is-
